Well we have the solenoid for the .5" air tank set to normally open so only when the arm+winch are being moved does the braking system disengage... when off it'll be braking. In order to slide down the motors would have to spin backwards w/o power and our braking system must fail... very unlikely although possible but 7 lbs of pressure being applied to that brake and the motors resistance will do well over hold our robot in position.
